Android Adds Fake Call Detection Using RCS

Android 17 will introduce real-time fake call detection in the Phone app, warning users if a caller is impersonating someone on their contact list. The feature uses end-to-end encrypted RCS technology to send a silent confirmation signal between devices, verifying the call's legitimacy. If the handshake fails, the app alerts users to end the call. This update builds on Android's 2024 scam call warning and enhances privacy through encrypted communication. Google Photos and Google Play Books also receive AI-powered updates, but the core change is in call verification. The feature ensures users are protected from impersonation attacks using secure, real-time device authentication.
